ABSTRACT
Oil paints, which are used in oil painting, are slow-drying, brush applicable and dye-based covering paints with pigment particles dispersed in thinners such as linseed oil. The viscosity of the paint that is in high viscosity and gel form can be adjusted by adding a solvent such as turpentine or spirits during use. After applying the paint, some varnish can be added to increase the gloss after drying on the canvas. In painting on canvas with oil paint, when the quality of the material is good, the paint is applied well and all the physical conditions are optimally applied, then the physical quality of the work will naturally be good. Visual and artistic quality is shaped proportionally according to the experience and talent of the artist. Some works that are painted physically in perfect condition and whose artistic values are considered indisputable by the society must be preserved and delivered to future generations without deterioration for many years. Therefore, these paintings, whose artistic and financial values are increasing day by day, must be taken care of under optimum conditions. Otherwise, the paintings that will naturally age over the centuries will unfortunately result in faster physical wear and therefore aging.
In the study, colour, material and visual quality losses were determined due to the good and bad storage conditions of two paintings that were made using the same materials under the same conditions 25 years ago. L*a*b* colour values of the paints on these two paintings were measured with Gretag Macbeth Spectrophotometer and compared with reference values, and also physical distortions and colour deviations were detected by examining the base material (canvas) images with a microscope.
